I actually have a half-constructed ancient language of my own. It is a syllabary and I haven't gone into any of the more advanced grammar and such. I just use it for individual words. The alphabet itself is very curved in style.

Which reminds me - I once read that the shapes of the letters tended to follow the medium on which they were most often used. For example: Roman and Norse script was most often (originally anyway) carved onto stones which is why it is made of straight lines and harsh angles. Arabic script and the like was more often written with brush on papyrus or paper so it could be more cursive. I suppose that is something to consider when creating an "alphabet" for a fictional people.
